Ruaidri Ó Gadhra

Ruaidrí Ó Gadhra, was an Irish king of Sliabh Lugha and Chief of the Name, died 1256.

During Ruaidrí's lifetime the territory of Sliabh Lugha was conquored by the Sheriff of Connacht, Jordan de Exeter (died 1258), ancestor of the Clan Mac Siúrtáin. Sliabh Lugha would from this time become known as Tir Mac Síurtáin (Mac Jordan's Country), in time becoming the barony of Gallen.

As a result of this, the Clan Ó Gadhra were forced north into Cuil Ui Fionn (barony of Coolavin, County Sligo), which would become their new home.

The Annals of the Four Masters record a number of incidents concerning the Ó Gadhra family during Ruaidhri's reign:

In 1256, Ruaidhri was slain by David, son of Richard Cuisin, who was apparently of the family that would go on to produce Ádhamh Cúisín, a scribe and genealogist who lived c. 1400 and was a compiler of Leabhar Ua Maine.

Ruaidhri was succeeded by Ruaidri Ó Gadhra.
